Ahh, that's mottling because you are using a straight paraffin. Add about 1 TBSP of stearic per lb of wax while melting and that would stop the mottling. You could also add vybar, but that's touchy and if you add too much you could bind your scent and get no scent throw.I add my scent and dye at 60 degrees then I stir thoroughly to make sure it's all mixed then I pour. Here's a picture of the frosting and the wax I use. Thank you for your help.
